He he, I can confirm this is much better. I don't really see a
difference with 1.x at first glance (while yesterday was painfully slow,
in my Cygwin/Xfree86 remote connection on an "old" FC2 Linux PC which is
maybe a bit peculiar).
Looking quickly at the diff, the only thing I saw that looked like more
than a cosmetic change was: 

+    painter->setRenderHint(QPainter::Antialiasing, false);

Was this really the cause of all slowness or have I missed something ???
